The NASA UAP independent study team recommends that NASA plays a prominent role in the whole-of-government effort to understand UAP by leveraging its extensive expertise to contribute to a comprehensive, evidence-based approach that is rooted in the scientific method. The team members specifically recommend that NASA utilize its existing and planned Earth-observing assets to probe the local environmental conditions associated with UAP that are initially detected by other means. In so doing, NASA can directly probe whether certain environmental factors are coincident with known UAP. They further recommend that NASA explore enhancing collaborations with the U.S. commercial remote-sensing industry, which offer powerful constellations of high-resolution Earth-observing satellites.

This image of the main-belt asteroid Dinkinesh was captured by NASA’s Lucy spacecraft on September 5, 2023. The brightest star in this field of view is HD 34258, a 7.6 magnitude star in the constellation of Auriga that is too dim to be seen by the naked eye from Earth. At this distance, Dinkinesh is only 19 magnitude, about 150,000 times fainter than that star. Image credit: NASA’s Goddard Space Flight Center / SwRI / Johns Hopkins APL.

This oblique perspective view of Lycus Sulci and Yelwa Crater on Mars was generated from the digital terrain model and the nadir and color channels of the High Resolution Stereo Camera on ESA’s Mars Express. It shows the large 8-km-wide Yelwa Crater in the background, while the wrinkled terrain of Lycus Sulci dominates the foreground. These features lie on the edge of the ‘aureole’ of Olympus Mons.

ESA’s Euclid spacecraft will orbit the second Lagrange point (L2), 1.5 million km from Earth in the opposite direction to the Sun. L2 is an equilibrium point of the Sun-Earth system that follows Earth around the Sun. In its orbit at L2, Euclid’s sunshield can always block the light from the Sun, Earth and Moon while pointing its telescope towards deep space, ensuring a high level of stability for its instruments. At L2, Euclid joins ESA’s Gaia mission and the ESA/NASA/CSA James Webb Space Telescope, which are also orbiting around this equilibrium point, each following well separated trajectories.
